Product details

Key voltage and power ratings for BOM fit

The 1.5KE200AHE3_A/D: The reverse standoff voltage (171 V) defines the maximum DC or peak operating voltage the device can withstand without conducting — above that, the TVS enters breakdown. Operating temperature range spans -55°C to +175°C, covering the full automotive underhood ambient and the self-heating margin during a surge.

Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mount. The leaded format is well suited for point-to-point wiring or PCB insertion in power distribution modules.

Frequently asked questions

What is the 1.5KE200AHE3_A/D used for?

It is a 1500 W transient voltage suppressor (TVS) diode designed to clamp overvoltage spikes on 24 V automotive power buses. The 171 V standoff voltage makes it suitable for systems where the nominal bus voltage is 24 V and the clamping threshold must be above the maximum steady-state voltage plus ripple.

Is the 1.5KE200AHE3_A/D RoHS and AEC-Q101 compliant?

Yes, it is AEC-Q101 qualified (automotive grade) and part of Vishay's TransZorb® series. Compliance documentation for RoHS and REACH is available from Vishay; the part is designed for automotive applications requiring PPAP-level qualification.

What package does the 1.5KE200AHE3_A/D come in?

It is supplied in a DO-201AA (DO-27) axial-lead through-hole package, shipped in Tape & Box (TB) format.
